⚠️ Label printing tiny / top-left? Tap here to fix (one-time setup)
In the print dialog (every time):
• Destination = Munbyn RW403B-N(Bluetooth)
• Margins = None
• Scale = 100% (or "Default" — NOT "Fit to printable area")
• Paper size = your label size
In Windows driver (one time — fixes tiny/corner):
Printers & scanners → Munbyn RW403B → Printing preferences → set paper/stock size = 57×32mm (match your label). This is the setting that stops it printing small in the corner.
PDF prints at the exact label size — best for correct sizing & alignment.
